Herd immunity means that the entire population (not just those who are vaccinated) are protected from a disease. What is one way that herd immunity protects an unvaccinated person (such as an infant who is too young to be vaccinated or a person who is immunocompromised)?
Why is the effectiveness of "herd immunity" so hotly debated within the SCIENTIFIC community
What is Herd Immunity and what is its Immunological and public health significance?
